let alone nifty achieving life time highs, it is unable to take out 52 week high when us markets have been hitting multi year highs. This in itself is a testimony to the underlying weakness in our markets. Your target is quite ambitious on nifty. Please read my post in the first page of this thread wherein i've already looked at the possibility if in case 5630 is taken out. Although nifty's co-relation with sp500 on the way up has not been intact, i expect it to be so on the way down.
